If anyone can identify these green buttons on the 319 pedestal (right above the throttle quadrant, inside the red box) I only seem to see them on U2 319.. What are the use and purpose of these buttons?

Yes. When the call is made from the cabin to inform the flight deck that the cabin is secured for either take off or landing, the slide is flipped over to the relevant side.

Seems like a pretty strange feature. Doesn't seem entirely necessary.

There are a LOT of things to keep track of. Anything that increases situational awareness and decreases pilot workload, especially with such a simple feature, should be encouraged.

It's the little things that will kill you...

"There are no stupid questions, but there are a lot of inquisitive idiots."

Many airlines use a similar indicator to show the autoland CAT status of the aircraft. It will be set by maintenance and will indicate if the aircraft has been downgraded in it´s autoland performance, e.g. because of a deferred defect.

Normally when one sees things like this, or strange SOPs unique to one airline, it is a result of an occurrence within that airline. Likely U2 had an incident where the aircraft took off or landed without the cabin being prepared.

Quoting SAAFNAV (Reply 14):
While on the terminology bandwagon, my pet peeve is when people are calling it 'finals' instead of 'final'.
There is only one final approach.

Incredibly pointless gripe, as you know exactly what someone means when they say "finals". It's also the official phraseology of the RAF so it's not incorrect. It actually originated as a shorthand for "miles final", e.g instead of saying "6 miles final" or whatever, you can just say "6 finals". That's where it's from anyway, not that anyone says it like that anymore.

So, like much phraseology in Aviation, it came about to a reason from a long time ago that isn't massively relevant now, but there's no harm in it.

Quoting BoeingGuy (Reply 2): The only "buttons" on a Flight Deck are on the pilots' shirts. There are Switches, Selectors and Keys on the flight deck.
